This is the ultrasonic jewelry cleaner that uses 42,000 Hz of ultrasonic sound waves to remove 99.8% of the debris from rings and necklaces. The Hammacher Schlemmer Institute soiled earrings, rings, and necklaces with a mixture of hair gel, hand lotion, and dirt and placed in an oven to solidify the detritus. An independent testing laboratory then weighed each piece after the soiling process and again after one cycle in this ultrasonic cleaner to confirm that it had removed 99.8% of the debris. The jewelry cleaner's ultrasonic sound waves and water (detergent is optional) penetrate deep into crevices and safely and effectively clean intricate areas of bracelets or watchbands. With an easy-to-follow instruction manual, a crystal clear LED screen with a digital timer, a watch holder, and an easily accessible 18-ounce water reservoir. 5 1/2" H x 8 1/4" L x 6" D. (3 lbs.)

I'd love to be able to leave my diluted cleaning solution in the container, but instructions say to wash it out each time. I end up losing much of the solution in trying to pour it out. (There's no easy way to do this).

I was not impressed when I first cleaned my jewelry, but my sister worked for a professional jewelry maker and told me that they used 409 to clean diamonds. It's a degreaser ... cuts handlotions, etc. and now I'm thrilled with the product!

I am so anxious to use this cleaner every time my necklaces and earrings need cleaning. I found out that I should put on my jewelry BEFORE I apply my makeup to eliminate any gunk or oil on my jewelry gets put it in the cleaner. The greatest thing about this cleaner is that no chemicals are used, only water. The vibrations alone clean my jewelry.

I used this product to clean dirt and try to remove some tarnish from silver. It works great to clean the dirt! Wow! Very nice although I had to run it several cycles with just water. It doesn't work to remove tarnish with just water but I'm going to try it with detergent. It does loosen the tarnish but doesn't remove it.

I make a lot of sterling silver jewelry. I wanted to find something quick and less harsh to clean my items. This unit did almost nothing when I put the silver in that had tarnished. I compared the machine "cleaned" items with ones that just got cleaned by the strong silver cleaner and it looked like the machine didn't do much of anything.

Returning the product!

Bottom LineNo, I would not recommend this to a friend

I was surprised at how easily the product is to use and how well it cleaned my jewelry. I also found it to do an amazing job on cleaning eyeglasses and sunglasses -- they are like new. The unit is the perfect size, doesn't take up too much room on the counter and is perfect for every day use.

It is also important to note that ultrasonic cleaners are designed to remove foreign substances, rather than specifically to shine. Most plastics should not be damaged in our ultrasonic jewelry cleaner, but it is not specifically designed for plastics. It is designed to clean metal objects. Materials should be tested before full cleaning to determine compatibility of the material with the cleaning agent. Pearls, paste jewelry, opals or opaque gemstones are also sensitive to this type of cleaning. No items should be placed directly on the bottom of the tank.
